Requirements for the power supply
Requirements for the power supply are as follows:
Table 2-4 Requirements for the electronic power supply
Parameter Requirement
Current 150 mA
1
per module (TM15)
1
Does not include the current provided for the DI/O or for the DRIVE-CLiQ Interface.
The maximum supply current for TM15 is calculated from the sum of the 3 currents below:
● 150 mA, maximum, via X524 connection
(module logic must always be taken into account)
● 450 mA, maximum, via X524
(24 V supply via DRIVE-CLiQ; relevant only if a module connected downcircuit of the TM15
is supplied via DRIVE-CLiQ, e.g. encoder without a separate 24 V connection)
● 24 x 0.5 A, maximum, via X520/X521/X522
(all channels are parameterized as DO and loaded with 0.5 A)
The terminal module monitors the electronic power supply for both overvoltage and
undervoltage conditions.
Note
Avoid long cables. The 24 VDC power supply should be located as close as possible to the
terminal modules. The total length of all power cables, when added together, must not exceed
10 meters.
